Plant diseases caused by Fusarium spp. will results in yield losses and are becoming more significant in Iran. In this study, infected plant samples suspected to Fusarium infection, plant debris and rhizosphere soil were collected from the most important crops that is, wheat, rice, corn, barley, potato, cucurbits from different provinces in Iran during 2002 to 2009. A total of 2,500 Fusarium isolates were obtained and classified into 30 species based on morphological characters. Fusarium sporotrichioides, F. chlamydosporum, F. graminearum and F. pseudograminearum were obtained only from tissue samples whereas F. scirpi, F. longipes and F. eumartii were from soils. Among the isolates, 41% were recovered from plant tissue, 36% from soil and 23% from plant debris samples. In cereals tissues, F. graminearum, F. pseudograminearum, F. sambucinum, F. culmorum, F. crookwellense, Fusarium proliferatum, F. verticillioides, F. fujikuroi and F. nygamai were predominant species. Fusarium spp. recovered from potato tissues were F. sambucinum, F. culmorum, F. crookwellense, F. trichothecioides, F. proliferatum, F. verticillioides, F. subglutinans and F. anthophilum whereas F. solani and F. oxysporum were predominant in cucurbits, sorghum, tomato, sugar beet and bean. To our knowledge this is the first comprehensive report on the identification of large number of Fusarium spp. in different crops from Iran. Key words: Fusarium spp., occurrence, distribution, agricultural crops, Iran.
